MILTON LOVE, OF O'ORRY, PENNSYLVANIA.

Letters Patent No. 109,433, dated November 22, 1870.

`IMPRCVEMENT IN MACHINES FQR THREADING BOLTS.

The Schedule referred to in these Letters Patent. and making part of the same.

To all whom 'it 'may concern Be it known that I, MII/rox Love, of the city of Corry, in the county of Erie, in the State of Pennsylvauia, have invented au. Improved Bolt-(lutter and Drill; and I do hereby declare the following to be an exact description thereof, vreference being had to the accompanying drawing and to the letters of reference marked thereon making a part of this speciication, in which- Figure l represents-a side elevation of the machine.

Figure 2, a longitudinal section of the saine.

The nature of my invention consists in the ar'- rangement of the devices of abinachine for cutting bolts and burs; also, for drilling by hand or other power.

loenable others skilled in the art to make and use my invention, I will proceed to describe its construct-ion and operation, as follows:

The machine has a hollow shaft, marked A in the drawing, held in position by journals l) b l), with a oog-wheel marked O, held in position. by means of journals marked b b.

The wheel has a key fastened iu it marked d, which holds it from turning on shaft A, which tits ina groove or seat, e, in shaft A, so as to let the shaft reciprocate backward or forward, and not let the wheel C move with it.

A screw, and wheel marked f f, with the ,hollow shaft A passing through it, formpart of one journal b,

The rear journal b has a screw cut in it to tit the screw with wheel f j' on the shaft A, so that when in operation it can be usedto reciprocate shaft A for drillingr purposes.

The hand or crank. h is fastened to shaft A on the rear end, foruse when'limited power' is required, or when light work is being performed in drilling or cutting small bolts.

I is a horizontal shaft, with bevel-gear J.

The bevel-gear is constructed so as to litor gear into wheel C.

Thc whole is heldin position by journals marked ened on the rear end of the shaft when greater power is needed.

The shaft A is intended to hold a head, N, on its front end, so constructed as to hold bolts or drills.

For this head N I make a separate application for Letters Patent, and specify in it said application.

The tail-block or rest W, which is used to hold the nut 4or bur when being cut, or a common stock or die, or a solid die for cutting bolts, or when in a reversed position, is used to drill against, is constructed as follows The tail-block or rest marked W is an uprightmow able square frame, with a rnortise through it marked S,so as to hold the die when cutting bolts, or a block to hold the different-sized nuts while being eut.

rIhe front of the block or rest W is so'constructed as to hold a-commou stock or plate by means of open hooks marked .X X.

The' upper part of block W rests at or near the center, on a pivot, Y.

'lhe end passing through the bottom of the rest lV is held in position by means of a thumb-screw marked L, in the lower part of the rest.

'Ihc lower part of ,rest W is constructed so as to work backward or forward in grooves marked and numbered 2 `2, thrilling guides or ways-to hold rest- W in au upright position.

0u the top of ways 2 2 are notches or teeth, constructe-d so as to let a lev'eiymarked 3, which-has two dogs, marked 4 4, passingthrough the bottom part of block V, preventing it from sliding back lwhen in use.

The grooved ways 2 2 are fast-cned on each side of l a through marked 5, which is used tocateh the waste oil.

Then in use the whole machine is intended to stand upon a bench of wood or other material.
